STEAM GAS- SPECIFICATION forming part of Letters Patent No. 271,874 dated' February 6,, 1883.

Application filed September 6,1882. (no model.)

To all whom it may concern Be it known that we, JAMES E. LEADLEY, of Camden, in the county of Camden and State of New Jersey, and JOHN -HANLON, of the city and State of New York, have invented certain Improvements in Steam Gas-Exhausters; and

we hereby declare the following to be a full,

ers, and has for its object to provide anapparatus wherein the vacuum will never be excessive, the gas is not reheated by the exhaust, and the exhaust-valve is more thoroughly controlled.

Our invention consists, first, in a compensatingvalve located between the by -pass valves, whereby the exhaustion is regulated;

second, in a spray apparatus introduced in one end of the exhauster to-prevent the jet from float, the raising or lowering of which quickly by displacement forces more or less water'into the tank containing the governor-cup.

In order that those skilled in the art may make and use our invention, we will proceed to describe the manner in which we have carried it out.

In the said drawings, A is the exhaust tube or pipe, and a the steam-jet pipe to produce the necessary vacuum. Above this pipe is the by-pass pipe B, in which is centrally located a housing or box, b,in which are located the bypass valves b b. Between the two valves b (2, against the diagonal seat (1, we set a swinging compensating valve, 0, which will open and compensate for any excess of exhauscounteract the heating effect of the steam, and thereby overcome the objections of reheating the gas. In fact, by experiment we find the gas at its exit is as cool as if a rotary exhauster were used.

When it becomes necessary to vary the volume of water in tank F, which contains float G, which is connected to and governs the throttle-valve H, after the manner well understood by those skilled in the art of constructing gas mental tank, I, alongside of tank F and communicating with it at its bottom through the passage f. A screw-rod, g,'passing through a yoke, h, on the top of tank I, carries on its lower end a hollow air-tight or solid cylinder, J, which by means of screw-rod 9 may be forced down into or withdrawn from cylinder the water by displacement in tank I, and obviously causing the same variation "in the height of the water in tank F. This afiords an easy and delicate adjustment for the valveoperating mechanism.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a steam gas-exhauster, the by-pass pipe B, having the by-pass valves b b, and a compensating-valve 0, arranged intermediate of the said by-pass valves, su bstantially as and for the purpose herein shown and described.

2. The combination, withthe'exhaust tube or pipe A, having the steamjet pipe at and the by-pass B, of the intermediate connectingchamber, D, provided with the vertical dia- E, arranged in said chamber, substantially as and for the purpose herein shown and described. 3. The combination of the tank having the 'float G, the connected throttle-valve H in pipe (1, and the supplemental tank I, communicating with tank F, near its bottom, and the vertically-adjustable cylinder J, arranged in the tank I, all constructed and arranged to oper' ate as herein shown and described.
